What is single flange butterfly valve?

A single flange butterfly valve is a type of valve used to control the flow of fluids in a pipeline. It consists of a disk-shaped body with a rotating disc or vane that acts as a damper to regulate the flow of fluid. The valve has a single flange on one end, which is used to connect it to the pipeline. The other end of the valve is typically sealed with a gasket. Single flange butterfly valves are commonly used in industrial applications, such as in water treatment plants, chemical processing plants, and power generation facilities. They are known for their durability, ease of installation, and low maintenance requirements.
